Engineered for heavy load-bearing architectural applications, our structural grade aluzinc steel coil delivers certified yield strengths ranging from S350GD to S550GD. Formulated to provide exceptional rigidity, dimensional stability, and anti-corrosion protection for steel framing, C/Z purlins, and industrial roofing systems.
Operating as the specialized international export division of Winroad Group, Authentic Steel manufactures certified structural grade aluzinc steel coils engineered specifically for heavy load-bearing architectural components, C/Z purlins, floor decking profiles, and light steel framing systems. Anchored out of the port city of Tianjin with a solid metallurgical background established in 1994 and a global supply network serving clients across 78 countries, our advanced cold-rolling and continuous hot-dip alloy coating lines maintain strict control over mechanical properties. Utilizing structural steel substrates (including EN 10346 S350GD/S550GD and ASTM A792 Grade 50/80), our structural galvalume coils deliver superior yield strength, seismic resistance, and structural integrity for industrial warehouses and modular housing frameworks.
Structural building components demand consistent mechanical performance under extreme wind loads and thermal expansion. Our structural aluzinc coils combine the barrier protection of aluminum dendrites with the sacrificial cathodic protection of zinc, ensuring that structural purlins and framing studs remain immune to atmospheric rusting over decades of exposure in unheated or industrial environments. The rigid metallic substrate withstands high-speed roll forming without cracking along profile bends.

Before any lot of structural grade aluzinc steel leaves our Tianjin plant, our quality assurance laboratory conducts strict yield testing, ultimate tensile strength measurement, elongation verification, and coating weight chemical analysis. We provide EN 10204 3.1 Mill Test Certificates with full heat batch traceability to ensure your structural engineering projects pass local building inspections without delay. All coils are packed with heavy-duty waterproof wrapping on solid wooden skids for international maritime shipping.
